I tried today with the GCN driver and it worked like a charm! I can finally play KOF XIV in my arcade machine :)Thanks Calamity for pointing me in the right direction
During my testing, I also realised why the Model 3 emulator was out of sync. It seems that its the monitor properties setting that is causing this issue.
When "hide modes that can't be shown in this monitor" checkbox is ticked, the model 3 emulator will work fine at 640x480.
But if this setting remains unchecked, it will display as if it was out of sync. Windows 7 64 detected my monitor as Generic monitor.
The only problem I have now, is that I enable this setting manually, but upon Windows restart, by default its disabled, so I need to set it up everytime I boot Windows 7. The settin isn't kept after every reboot, it seems to revert to a default "disabled" value.
Is this a driver issue? Has anyone been through this before?
Thanks again!!!
